Not sure ancient historicals are your thing? Give Body Language a try. It's a prequel to my Apollo's Men series. And as it's free, a good way to get your feet wet.
Travelling with Narses through conquered Lydia, Lykos hides his identity as a prince of Aenus. He intends to take the measure of the encroaching Persian Empire. But before they reach Sardis, he hears cries for help and charges into battle with mountain bandits. Unable to save the beleaguered merchant, he rescues Kas, a young Persian man.
Now his protector is dead, Kas would like nothing better than to remain with the handsome warrior who came to his aid. But how can he explain that to a man who speaks little but Greek?
